SPECIFICATION forming part of Letters Patent No. 488,604, dated December27, 1892.

Application filed April 9, 1892- Serial No. 428,468. (No model.)

To all whom it may concern.-

Be it known that I, KARL THEODOR ER- HARD, of Brooklyn, Kings county,NewYork, have invented an Improved Holder for Eras ers, Chalk, or Crayons,of which the following is a specification.

This invention relates to a holder for a rubber eraser, chalk, crayon orsimilar article and which permits its charge to be gradually projectedoutward or drawn inward, by turning a screw. Thus the holder alwaysoffers a sufficient grasping surface and at the same time insurescleanliness, as it prevents directcontact between its contents and thehand.

The invention consists in the various features of improvement more fullypointed out in the claims.

In the accompanying drawings Figure l is a top view of my improvedholder. Figs. 2 and 3 are longitudinal sections thereof on line m, to,Fig. 1, showing the slide in different positions. Fig. at is a rearviewof the holder. Fig. 5 a cross section on line y, y, Fig. 1, and Fig.6 a perspective of the slide.

The letter a, represents a case of suitable material and form and openat its front a, for the admission of a rubber eraser, chalk, crayon orsimilar article A. Within the case a, there is free to move backward andforward a slide 1), provided with outwardly opening spring jaws b, andwith a tapped projection or nut 13 This nut is received by alongitudinal groove or channel a formed in one of the sides of case a.

c, is a screw shank engaging the nut b and of asize to fit Within thechannel (1 At the back of the case, the screw projects out- Wardlythrough a perforation and is there provided with afolding handlec. Toaccommodate this handle when folded down, the back of, of case a, isprovided with a central recess (1 Thus the holder can be convenientlycarried in a pocket.

The operation of the device Will be readily understood. When the screwis turned in one direction it will draw the slide 19, and its charge A,into the case to any desired extent. When turned in the oppositedirection, it will push the slide forward and project the chargeoutward. Thus it will be seen that as the rubber or similar article isused up,it can be fed outward to a corresponding degree. When not inuse, the rubber may be drawn entirely into the case to be protectedagainst contact with the hand or pocket.

That I claim is:

1. The combination of a case with an inclosed tapped slide havingoutwardly opening jaws that are adapted to grasp the eraser, chalk orcrayon and a screw that enters the case and engages the slide,substantially as specified.

2. The combination of case at, having rccessed back a with slide 5,having nut b and with screw 0, engaging said nut and having Y foldinghandle 0, substantially as specified.

KARL THEODOR ERHARD.
